Application March 23, 1950, Serial No. 151,477

6 Claims.

This invention relates to a bung and pintle assembly for shade rollers and the like, and more especially to a unitary structure which is automatically centered and secured when inserted in the roller. I

One of the prime objects of the invention is to design a unitary bung and pintle assembly for insertion in the open end of a hollow shade roller, 'and by means of which the roller is supported in accurate alignment in the conventional bracket mounted on a window frame or casing.

Another object is to design a neat-appearing, substantial unitary bung and pintle assembly provided with resilient serrated legs for yielding frictional engagement with the interior of a shade roller when in assembled relation.

Still a further object is to design a bung and pintle structure including a cup-shaped ferrule in which the end of a roller is inserted together with indents in the face of said ferrule for piercing the end of said roller.

A further object still is to provide a bung and pintle assembly including a bearing washer on the pintle for engagement with the face of the ferrule, said pintle serving to firmly secure the a various parts in assembled relation.

A further object is to provide a simple, durable and relatively inexpensive bung and pintle assembly, which can be economically manufactured and assembled, and which can be easily inserted in the end of a roller without the use of tools of any nature.

To the accomplishment of the foregoing and ,related ends, said invention then consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and following description setting forth, in detail, certain means and one mode of carrying out the invention, such disclosed means and mode illustrating, however, but one of the various ways in which the principle of the invention may be used.

In the drawing:

Fig. l is a fragmentary, face-elevational view of a window frame showing a shade and roller with my approved bung and pintle assembly mounted in one end of the roller. I

Fig. 2 is a fragmentary, vertical section through one end of a shade roller with the bung and pintle assembly in position therein.

Fig. 3 is an end-elevational View of the bung and pintle assembly.

Fig. 4 is an isometric view thereof.

Fig. 5 is a transverse-sectional view taken on the line 55 of Fig. 2.

Referring now more specifically to the drawing wherein like characters indicate corresponding parts throughout the several views thereof; in Fig. 1 of the drawing I have shown a Window frame 6 having inside brackets l mounted thereon as usual. I

A shade roller 8 is mounted in the brackets 'J' and a shade 9 is wound on the roller in the conventional manner. The roller 8 can be formed of paper, wood, or any other similar material;

it can be hollow throughout its length as india ferrule F formed with a rim cated at III, or the end sections only can be hollow if desired.

A unitary bung and pintle assembly B is mounted in the end of the roller 8 and includes l I of a size to snugly fit over the end of the roller, the face of the ferrule being concentrically ribbed as at 2, and a centrally disposed opening i3 is provided therein as shown, inwardly projecting indents M being provided in said ferrule, said indents piercing the end of the roller 8 for anchoring the assembly in position.

A pintle member I5 is mounted in the ferrule F, and is provided with a shoulder l6 intermediate its length, a washer bearing ll being mounted onsaid spindle adjacent said shoulder and is of a size to fit and nest in the area defined by the concentric rib I2, the pintle extending through the ferrule and through a U-shaped member C, the end of the pintle being headed iover to firmly secure the parts in assembled relaion.

The upper end wall l8 of the member C is disposed in facial contact with the inner'face of the ferrule F, and includes spaced-apart, elongated, resilient leg members [9, the edges of which are serrated as at S, the free ends of the legs being inwardly bent as at 20, each inwardly bent section being cutaway as at 2i to form tips 22, said tips being reversely bent, so that when the legs are forced into the hollow end of a shade roller 8, these tips will slide on each other with the edges of the legs biting into the interior surface of the roller to non-rctatably secure it therein.

The legs 19 are ribbed as at 23 for reinforcing purposes, and I wish to direct particular attention to the fact that the serrated edges only of the legs engage the inner surface of the roller, and these edges, together with indents i l, firmly secure the assembly in position, all as clearly shown in Figs. 2 and 5 of the drawing.

The Structure is completely assembled prior to mounting, it is merely inserted in the roller with the rim l2 fitting over the end as shown.

From the above description, it will be apparent that I have produced a construction embodying all of the features of advantage set forth as desirable, and it is to be understood that I reserve the right to all changes within the scope and spirit of the appended claims.

What I claim is:

l. A unitary bung and pintle assembly for shade rollers comprising a ferrule provided with" a centrally disposed opening therein, a U-shaped member mounted in said ferrule against the inner face thereof and formed with elongated resilient legs, the free ends of which are bent toward each other, and a centrally disposed, shouldered pintle mounted in saicf ferrule and U- shaped member and firmly securing the parts in assembled relation.

2. The combination defined in claim 1 in which the legs are longitudinally ribbed, the ends of the bent sections of the legs yield-ingly engaging each other when the legs are inserted in a shade roller.

3. The combination set forth in claim I in which the bent end sections of the legs are cut away to form reduced end tips, said tips being reversely bent for sliding engagement with each other when the assembly is inserted in a' roller.

4 The combination stated in claim 1- in which a bearing Washer is interposed between the shouldered section of the pintle and the face of the ferrule, the face of the ferrule being concentrically ribbed to center and nest said washer.

5. The combination defined in claim 1 in which the edges of the yieldable legs are serrated for frictional engagement with the inner surface of a hollow roller member;

6. A bung and pintle assembly including a ferrule formed with a centrally disposed, concentric rib, inwardly projecting indents formed in the face; of said ferrule, a centrally disposed washer nested in the area defined by said rib, a, U-shaped, member disposed against the inner face of the ferrule and formed with spacedapart resilient legs, and a shouldered pintle extending through said washer, ferrule and U- shaped. member for firmly securing said members between said pintle shoulder and the end of said pintle.
